A living enzymatic adenosine switch couples metabolic rescue to IL-12-driven antitumor immunity

This study presents a modular living immunotherapeutic strategy using tumor-tropic *E. coli* engineered to surface-display adenosine deaminase and interleukin-12, which locally converts immunosuppressive adenosine into T-cell-fueling inosine while simultaneously stimulating immune responses to effectively control diverse hematologic and solid tumors.

Embryonic origins of epigenetic mosaicism in the human colorectal epithelium

By analyzing single-cell clones from human colorectal epithelium, this study reveals that the majority of lifelong somatic epigenetic mosaicism (~60%) originates from stable, lineage-specific epiallelic commitments established during early embryogenesis rather than from age-associated stochastic mutations, with significant functional consequences for gene expression and developmental phylogeny reconstruction.

Regulation, function and evolutionary structure of St18, encoding a Zinc-Finger Transcription Factor, in the oligodendrocyte lineage

This study identifies the zinc-finger transcription factor St18 as a critical regulator of oligodendrocyte differentiation and myelination, demonstrating its evolutionary emergence in jawed vertebrates alongside the development of myelinating oligodendrocytes and its regulation by core transcription factors like SOX10.

Self-Calibrated Hyperspectral Neural Radiance Fields for 3D Reconstruction of Bone and Bone Analogues

The paper introduces BoNeRF-HS, a self-calibrated hyperspectral neural radiance field framework that enables high-quality, pose-free 3D reconstruction of bone and bone analogues by jointly optimizing camera intrinsics and spectral radiance while leveraging a gated spectral adapter to capture wavelength-dependent tissue details.

Auxin and Cytokinin Differentially Regulate Growth, Bud initiation, and Leaf Morphology in the Dryland Moss Syntrichia caninervis Brid

This study demonstrates that while auxin and cytokinin exhibit partially conserved, antagonistic roles in regulating growth and development in the dryland moss *Syntrichia caninervis*, species-specific hormonal sensitivities offer promising strategies for biocrust restoration in dryland ecosystems.

Identification and applicability of azg1 as counter-selectable marker in Trichoderma species

This study establishes the endogenous gene *azg1* as a versatile counter-selectable marker and expands the genetic toolkit for *Trichoderma* species by enabling efficient targeted integration and engineering through CRISPR/Cas9-mediated disruption of 8-azaguanine uptake and heterologous sensitization to 5-fluorocytosine.
